def savePartition(getConnection: () ⇒ Connection, table: String, iterator: Iterator[InternalRow], rddSchema: Array[DataType], tableSchema: StructType, dialect: JdbcDialect, batchSize: Int, upsert: Boolean): Unit

Saves a partition of a DataFrame to the JDBC database.
Saves a partition of a DataFrame to the JDBC database. This is done in a single database transaction in order to avoid repeatedly inserting data as much as possible.
It is still theoretically possible for rows in a DataFrame to be inserted into the database more than once if a stage somehow fails after the commit occurs but before the stage can return successfully.
This is not a closure inside saveTable() because apparently cosmetic implementation changes elsewhere might easily render such a closure non-Serializable. Instead, we explicitly close over all variables that are used.
def saveTable(df: DataFrame, table: String, tableSchema: StructType, connProperties: ConnectionProperties, upsert: Boolean = false): Unit

Saves the RDD to the database in a single transaction.
def schemaString(schema: StructType, dialect: JdbcDialect): String

Compute the schema string for this RDD.
